VGA display - DE2I150 and NIOS

Hi Guys,

I am a newbie to NIOS. I am trying to access an image in SD card, store it onto SDRAM and finally display it on VGA.

I am able to detect the SD card,read the image file. I guess I'm able to write successfully it onto SDRAM. But I am not able to display it on VGA. I have attached the c code and qsys system I am using. Could you please point out where I am going wrong.

Thanks...
